Asahi Tanker to start ship fueling with world's first electric tanker
Japan's Asahi Tanker said it will start using the world's first electric-powered tanker for ship fueling, known as bunkering, later this month in an effort to cut carbon emissions.
Japan, which is the world's fifth biggest CO2 emitter, aims to achieve carbon neutrality by 2050, while the global shipping industry, which relies on oil to power its vessels, is trying to speed up efforts to reduce emissions of GHGs.
"The vessel's core energy system is completely electrified to achieve zero emissions of CO2, nitrogen oxide and sulfur oxide," Makoto Sawada, team leader of the EV project at Asahi Tanker said.
"With less vibration and noise, the new ship is also aimed at improving the work environment for the crews, which may be a solution to a shortage of Japanese crew members mandated for coastal vessels," he said on the sidelines of the opening of an electricity charging station in Kawasaki, near Tokyo.
The 62-meter-long tanker, which is powered by large-capacity lithium ion batteries, can sail around 100 kilometres when running at about 10 knots after a full charge of electricity.
The vessel was completed in March, with a cargo capacity of about 1,000 kiloliters of marine oil and battery capacity of 3,480 kilowatt hour or about 100 batteries for a typical electric vehicle.
The charging station, operated by a Tokyo Electric Power unit, was built in Kawasaki's main industrial zone.
The new vessel deliver marine fuel from refineries to larger tankers or cargo ships in Tokyo Bay roughly once a day, after charging overnight, said Asahi Tanker, adding that it plans to operate a second electric tanker next year.
Building an electric tanker costs about 1.2 B yen ($9.6 MM), compared with 750 MM yen to build a conventional one. Asahi Tanker hopes to cover this by offering companies a cleaner bunkering service, Sawada said.
